Chamaedaphne calyculata / Carex striata - Woodwardia virginica Wet Dwarf-shrubland
Translated Name: Leatherleaf / Walter's Sedge - Virginia Chainfern Wet Dwarf-shrubland
Common Name: Low Wet Leatherleaf / Sedge - Chainfern Pocosin
Unique Identifier: CEGL004163
Classification Approach: International Vegetation Classification (IVC)
Summary: This dwarf-shrubland is found in North Carolina in peat-burn openings and other mucky depressions in low, medium, or high pocosins, sometimes forming a mosaic with various shrublands. Individual patches are usually small but sometimes abundantly intermixed with low pocosin shrub vegetation. Vegetation is dominated by Chamaedaphne calyculata, Carex striata, and Woodwardia virginica, but lacks abundant Vaccinium macrocarpon or Sarracenia spp. Other characteristic species include Eriophorum virginicum, Calamovilfa brevipilis, Utricularia subulata, Lysimachia asperulifolia, Peltandra sagittifolia, and other shrubs (scattered).

NatureServe Conservation Status
Global Status: G1G2 (31Dec1997)
Rounded Global Status: G1 - Critically Imperiled
Reasons: This saturated shrub herbaceous association is only found in a restricted range and specific set of habitat conditions. It consists of herbaceous openings in peat burns and other mucky depressions in low, medium, or high pocosin, with scattered to fairly extensive mats of shrubs. It is restricted to the outer Coastal Plain of North Carolina. Threats include alteration of fire regimes (suppression and exclusion), alteration of hydrologic regime (ditching and draining), conversion to commercial forestry plantations, and land-use conversion.

Environmental Setting

Dynamic Processes

Dynamics: This community results from catastrophic fires in large blanket bog pocosins; such fires are not legal as prescribed fire, and now only occur as wildfires which are aggressively suppressed. This community may be considered a "fugitive," one which requires catastrophic disturbance to establish it, and since these disturbances are suppressed, its future is uncertain.
